I was expecting to have to port forward too and yet our setup doesn't require it, not on the laptop nor on the wireless router.
I think as long as the SIP clients open a port on the NATing device and keep them open so the SIP provider can connect to it, all is well, even if STUN isn't used. I was surprised by how easy it was to NAT the Grandstreams. I had visions of having every device being assigned a static IP and having a fistful of port forwards assigned to them on the router.
